Application May 11 1956, Serial No. 584,295 Claims. (Cl'.132,l39)

This inventionrelates to hair curlers, and is designed for use inpreparing home permanent waves as Well as nightly pin-ups.

An important object of the invention is to provide means to eliminatethe use of end papers and objectionable solutions that are applied bydaubing a cloth or cotton saturated with the solution on the hair.

Another object of the invention is to provide a curler including asponge roller adapted to be saturated with the liquid used in hairtreatment, so that when the hair is wound on the roller in forming acurl, the curler will capture and hold all brittle ends of the hair andat the same time, saturate the curl from the inside out, with thesolution being used.

Another important object of the invention is to provide a curler whereinthe head rests on the sponge portion of the curler and it does not reston the rigid portion of the curler when the curler is used for nightlypin-ups, thereby lending to the comfort of the user.

Still another object of the invention is to provide a sponge coveredroller having a spiral groove formed at one end of the shaft of theroller, for the reception of the bearing of the curler frame withinwhich the shaft operates, so that the lock of hair wound on the spongeroller will be tightened on the roller as the sponge roller rotates whenthe head of the person wearing the curler is moved over the .pillow,during the sleeping period.

Other and further objects and advantages of the invention will behereinafter described and the novel features thereof defined in theappended claims.

Referring to the drawing:

Fig. 1 is a side elevational view of a curler, constructed in accordancewith the invention.

Fig. 2 is a plan view thereof.

Fig. 3 is a longitudinal sectional view through the curler. V

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1.

Fig. 5 is a sectional view taken on line 5-5 of Fig. 1.

Fig. 6 is an end view of the curler.

Referring to the drawing in detail, the curler comprises a substantiallyU-shaped frame indicated generally by the reference character 5,including a bight forming a bar 5, the end 6 of the frame beingbifurcated at 7. The bifurcated end is provided with aligning bearingopenings 8 to accommodate the bore 9 which is held in said bearingopenings by frictional contact.

The other end 10 of the frame is also bifurcated and is provided withshort ribs 11 that extend inwardly from the bifurcations thereof, theshort ribs 11 being designed to fit Within the spirally formed grooves12 as formed in one end of the shaft 13 for the purposes to behereinafter more fully described.

The shaft 13 provides a support for the sponge roller 14 which issecured to the shaft 13 to rotate therewith.

As better shown by Fig. 3 of the drawing, the shaft 13 is of a length toextend beyond the end 10 of the frame 5, where it is provided with aknob 15 afiording U i d tateme Patented Dec. 2, 1958 2 means foreffecting rotation'of the shaft 13 and sponge roller 14.

The roller 13 is substantially oval in cross section as better shown byFigs. 4, 5 and 6 of the drawing, so that when the roller 14 is moved inone direction, the thicker portion of the roller will move'closer to theframe 5 thereby tighteningthe curl on the roller.

Thus it will be seen that due to this construction, as the personwearing the curler moves her head during the sleeping period, the rollercontacting with the pillow will cause the roller to rotate tighteningthe curl.

In using the curler, the sponge roller is dipped in the solution toabsorb the necessary quantity of the liquid. The lock of hair is nowrolled on the roller in the usual way to form the curl and the shaft 13is forced between the-bifurcationsof the end 10 of theframe to grip theshaft in a manner as described, with the short ribs 11 disposed withinthe grooves'12, locking the shaft against movement.

The pressure caused by rolling the lock of hair on the oval spongeroller to move the enlarged portions of the oval sponge roller to clampthe hair between the roller and bar 51' resulting in the hair treatingsolution being forced from the sponge roller to cause the lock of hairto become saturated with the solution from the inside out, and willcontinue to supply the hair treating solution to the hair as pressure isdirected to the roller.

It will also be noted that the tension created by the tendency of thecurl to unwind, working against the natural tendency of the short ribs11 disposed with in the spiral grooves 12 to hold the shaft 13 androller against movement, will create pressure squeezing the lotiontherefrom.

It will of course be understood that the frame 5 is constructed ofsemi-rigid material capable of slight flexing so that the shaft 13 maybe readily and easily removed or replaced as desired.

Having thus described the inventionwhat is claimed 1. A hair curlercomprising a substantially U-shaped body including ends and a bight,said bight forming a bar, bearings carried by said ends, a shaft mountedfor rotation within said bearings, a roller constructed of absorbentmaterial secured on said shaft adapted to be saturated with hairtreating lotion, said roller operating in parallel spaced relation withsaid bar clamping hair therebetween, said roller being oval in crosssection providing a thick portion and a thin portion, said shaft havingspirally formed grooves adjacent to one end thereof, ribs extending fromthe hearing at one end of said bar cooperating in said grooves adaptedupon flexing of said bight to extend the legs of said U-shaped body torotate said roller in a direction to position said thick portionadjacent said bight in order to clamp a lock of hair between said rollerand bar, squeezing the lotion from said roller into the lock of hairwrapped on said roller, treating the hair and forming a curl.

2. A hair curling device comprising a frame including a bar, a shaftrotatably mounted on said frame in spaced relation with said bar, asponge roller having an oval cross section providing a relatively thickportion, secured on said shaft to rotate therewith in clamping a lock ofhair saturated with hair treating lotion wound on said roller betweenthe roller and bar in contact with said bar, and mechanism normallyholding said shaft and roller against movement but adapted upon flexureof said frame to rotate said bar to juxtapose said thick portion to saidbar for squeezing the lotion from said roller upon application ofpressure to said roller saturating the lock of hair wound thereon.

3. A hair curling device comprising a frame including a bar, a shaftrotatably mounted within said frame in parallel spaced relation withsaid bar, an absorbent roller, oval in cross section providing athickened area, secured on said shaft adapted to be saurated with a hairtreating lotion, and, on which a 10d; ,ofhair is rolled, andmec'hanisrnforeffecting rotation-of said roller relative to said, framewhereby said thickened area moves into clamping relation withsaid bar,squeezing lotion from the roller onto th lock of hair rolled thereontreating the lock of hair in forming a curl.

4. A-hair curling devicecomprising a U-shaped frame including a bar, ashaft having-one of its ends rotatably mounted at one of its ends onsaid frame, a bifurcated bearing on said frame, one end of said shaft.being removably held within the furcations of said bearing, anabsorbent roller, oval in cross section providing a'thickened section,secured on said shaft, and said roller adapted to cooperate with the barwhen said shaft is rotated to juxtapose said thickened area to said barin clamping a lock of hair wound on said roller in forming a curl,squeezing lotion from said roller to the lock of hair as said roller isrotated.

5. A hair curling device comprising a U-shaped frame including amain'bar, a shaft rotatably mounted on said frame, a roller, oval incross section providing thickened roller area, secured on said shaft torotate therewith, said roller being constructed of absorbent materialadapted to contain hair treatinglotion, mechanism at the end of saidframe in contact with said shaft for effecting movement of -saidrollerwhereby said thickened area of said -roller-moves towards said bar inclamping relation therewith upon rotation of said shaft and roller bycontact of-said roller with the head of the wearer while the frameisheld stationary.
